IMPRCVEMENT IN LIME-KILNS.

The Schedule referred to in than Letters Patent and making part of the same.

= taken aty y of iig. 3.-

vFigure represents a. plan of same, at the line .zvz

of figs. 1 and 2.

Similar letters indicate like parts.

rIhe object of my invention is to economize space and material-in constructing, and fuel and labor in operating lime-kilns, and- I laccomplish it by uniting several cupolas or kilns in one stack, and by other details hereinafter' set forth.

A, in the several figures, represents a stack, built of brick, rectangular in form, and suiiiciently large to be divided internally, by two transverse partitions, B.

O, at right angles to each other, into four cupolas, D, which number, experience tells me, is most advantageous, though, of course, this may be increased, if desired, by simply adding other partitions, and increasing the size of the'stack.

The wall B is .made somewhat thicker and higher thanO, though both are considerably lower than the top' of the stack.

Both stack and dividing-walls may be lined with fire-brick in the usual manner.

G, in the several figures, represents the furnaces, of which there are two to each compartment, extending into the stack, one on either side of the compartment, to the back of same, and there connecting with it by lateral passages K. d

The entrances of the furnaces are lined with tirebrick or clay frames H, let into the walls, flush with the surface of the same, and the peep-holes I are also lined with tire-clay.

By means of .passages L, leading from the front of the furnaces, the cupolas are 'supplied with fresh air for mixture with the gases beyond the .tire-bed;

Now, in order to dispose of the increased production of a kiln of this'kind, without a corresponding increase of manual labor, which is 'a needed improvement in those kilns now in use which unite several cupolas in one stack, I arrange the delivery-chutes E, at the bottom of the cupolas, in a recess, as seen in fig. l, the chutes being extended, however, beyond the wall of the stack, at a sufficient height to allow a wagon beneath it, to receive its deposits, Awhile that portion of the continuation of the chute within the recess is provided with a screening-grate, E', so that t-he screenings may fall into aA receptacle placed in the recess to receive them, so that one and the-same operation discharges the cupolas, screens the charge, and loads the wagons with the pure and clean lime; thus vsaving materially the amount of labor required.

Suitable doors -fare provided above the chute, to regulate the drawing of the charges; and to. protect the brick-work, the chutes are lined with boiler-iron. I, of course, do not claim, generally, the arrangement of two or more cupolas in one stack, since kilns now in use possess this feature; but

XVha-t I d o claim as my invention, and desire to secure by Letters Patent, is v The combination, with the cupolas D, of dischargechutes E and screening-grates E, arranged in recesses in the side of the stack A, and constructed and operating substantially as and for the purpose shown and specified.
